Why would you think there's a networking issue? The error message clearly states that a data value isn't present. You may want to run your code under the debugger and monitor the variable(s) of interest at different locations of your program until you find where the error is.

By the way, I've not seen anyone use an asterisk in a hash key like that. What do you suppose that is doing? Amusing, I don't recall seeing people intentionally use the stringified reference for a hash key!

Finally, if your issue is that you don't know why the code is trying to close the connection, then it's not terribly helpful to see only the closing logic. By that point, the decision to close has *already been made*, and you're just showing us what's being executed after the incorrect decision.

Since you've added your code to your post, I looked it over, and I don't see any obvious problems. Are you running it directly from the command line? If not, perhaps a helpful error message is getting swallowed somewhere and not showing up.

Update: I've added the italicized bits after the OP added more code to his post.
